Mass Transfer Pick out the wrong statement. Raoult's law does not apply, when the Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar Chemical combination or molecular association between unlike molecules takes place in the formation of solution Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar Chemical combination or molecular association between unlike molecules takes place in the formation of solution ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer A distillation column with N plates is being operated under normal conditions. At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped). At the new steady state, Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available Composition of vapors and that of liquid do not vary throughout the column Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available Composition of vapors and that of liquid do not vary throughout the column ANSWER DOWNLOAD EXAMIANS APP
